[ofa-general] [PATCH] rdma_cm: fix port type (fix bug 557)

[Yosef Etigin]

This fixes bug 557 <https://bugs.openfabrics.org/show_bug.cgi?id=557>

If next_port is signed int, and is randomized to be negative, it will fail
accesses to the idr data structure and therefore cause errors in rdma_cm users.
